Configuring a LAC-to-LAC IPv6 tunnel

Sample LAC-to-LAC IPv6 tunnel shows the topology of a sample L2TPv3 LAC-to-LAC IPv6 tunnel configuration. To configure this sample LAC-to-LAC tunnel, perform the following steps in configuration mode:

  1. Configure the L2TPv3 tunnel and LAC cross-connect settings on the R1 router.
    1. Configure the L2TPv3 tunnel settings (Configuring the L2TPv3 settings for a LAC-to-LAC IPv6 tunnel on R1).
    2. Configure the LAC cross-connect settings (Configuring the LAC cross-connect settings on R1).
  2. Configure the L2TPv3 tunnel and LAC cross-connect settings on the R2 router.
    1. Configure the L2TPv3 tunnel settings (Configuring the L2TPv3 tunnel settings on R2).
    2. Configure the LAC cross-connect settings (Configuring the LAC cross-connect settings on R2).
